At zero temperature, the superfluid Fermi liquid self-consistency equations that describe superposition of states with singlet and triplet fermion coupling are obtained and analyzed. The conditions for creating such states are found. Equations for the critical temperature of the phase transition from a one-gap (singlet or triplet) superfluid state to a singlet-triplet superfluid state and the temperature dependence of the order parameters near the transition temperature are derived. A mechanism for creating new states is proposed, and the thermodynamic stability of these states is studied.
